CROSS REFERENCE TO RELATED APPLICATIONS This is a continuation-in-partof my copending application, Serial No. 803,713, now abandoned, filedMar. 3, 1969.

BACKGROUND OF THE INVENTION This invention relates to mounting apparatusfor securing a sighting device, such as a telescopic sight to a gun.More particularly, it pertains to mounting apparatus secured to the topsurface of a gun receiver assembly and including an aperture forimproved metallic or barrel sighting.

Rifles and similar firearms are ordinarily furnished with metallicsights which comprise a front and rear upstanding members mounted on thetop surface of a gun barrel. The tops of the members are aligned fordirecting a fired bullet to its target. Metallic sights are usedprincipally for short distances while, for longer distances, atelescopic sight, mounted on top of the gun, is used. In hunting, barrelas well as scope sights must be equally convenient and available to therifleman.

Accordingly, it is an object of this invention to secure a telescopicsight to the top of a gun barrel without the necessity for obscuring orhindering the use of barrel top sights.

It is another object to furnish a scope mount which also functions as athird barrel sighting member useable with conventional metallic sights.

Yet another object is to provide a unitary mounting assembly having acontinuous curved interior surface member adapted to reflect ambientlight along a sighting axis.

A further object is to reduce the cost and complexity of mounts fortelescopic sights.

SUMMARY OF THE INVENTION The foregoing and other objects are attained inaccordance with a specific illustrative embodiment of the inventioncomprising an elongated C-shaped member having a bottom curved surfacefor interfitting with the top surface of a gun receiver assembly. A topsurface of the member is shaped to accommodate the telescopic sight andits mounting apparatus.

Importantly, the interior surface of the member, also havingsubstantially a C-shape, outlines the rear and front metallic sights asviewed from the conventional sighting angle, i.e. from the rear of therifle. When the tops of the barrel top sighting members are aligned,they appear at the center of the outline formed by the grooved interiorsurface, thus, enabling the user facilely and with enhanced accuracy toutilize existing sighting means.

A unique advantage of the mount assembly is the fact the side opening ofthe mount enables ofl-target game to be continuously and simultaneouslyviewed until the barrel sights are aligned on the game. Moreover, theinterior surface of the mount is curved and light reflective.Principally because of the curvature of the interior surface, reflectedlight is focused and concentrated so that ambient light bathes theviewing axis. Therefore, there is no substantial change in lightingconditions whether a quarry is viewed in sight alignment or outside themounting assembly.

A manifest advantage of this mount is that it enables the rifleman torapidly verify the accuracy of the telescope without the necessity forsighting through the barrel. In prior arrangements in which the mountingof a scope sight obscured the barrel sights, it was necessary topartially disassemble the weapon in order that a sighting could be madethrough the barrel for checking the accuracy of the scope. With myinvention, the scope sight adjustment may be verified and correctedsimply by comparison with a metallic sighting since my mount does notobscure the barrel sights.

In an alternative embodiment of my invention a portion of the bottomsurface of the mount is removed and another portion of that surface hasa greater thickness to accommodate those rifles which load shells fromthe top of the receiver assembly. Advantageously, the features andobjects described above are contained in this particular embodiment aswill be hereinafter described.

DESCRIPTION OF THE DRAWING The foregoing and other objects, features andadvantages of this invention will be more clearly understood from areading of the following description with reference to the drawing inwhich:

FIG. 1 sets forth a side view of a rifle 21 together with a telescopicsight 20 secured by scope mount 1 to a receiver assembly 25,

FIG. 2 is a perspective view of scope mount 1;

FIG. 3 is an end sighting view through mount 1 showing the positioningof front barrel sight 23 and rear sight 22 when properly aligned; and

FIG. 4 depicts an alternative embodiment of mount 1 for top loadingrifles DETAILED DESCRIPTION Referring to FIG. 1, it shows thepositioning of mount 1 on rifle 21. As may be seen barrel sightscomprising members 22 and 23 are viewed through mount 1. To utilize thescope 20, the rifleman elevates his eye as shown in the figure.

Considering mount 1 in greater detail and with reference to FIG. 2, itis an elongated and a substantially C-shaped assembly. Barrelinterfitting surface 5 is curved over the length of the assembly. Thecurvature of surface 5 conforms to that of receiver assembly 25 (FIG.1). The interior surface 2 is also substantially C-shaped and has agrooved interior running the length of mount 1.

Mounting holes 1013 are counter-sunk to provide for flush mounted screws(not shown) which secure mount 1 to receive assembly 25.

Positioning of holes 1013 is determined by the position of threadedholes in assembly 25 which threaded holes are ordinarily furnished bythe rifle manufacturer to accommodate scope mounting. Thus, yet anotherimportant advantage of the invention is that it does not requireadditional drilling in the gun barrel for fastening mount 1 to assembly25. Access holes 14-17 are aligned vertically with respective holes10-13 and have sufficient diameter to allow insertion of a tool throughholes 14-17 to tighten or loosen-the mounting screws in holes 1013.Advantageously, since the side of mount 1 is open for its entire length,positioning of mounting screws in holes 1013 may be done facilely byhand.

Bevel faces 6 and 7 are shaped to receive a convention mounting bandlooped around the telescopic sights situated on top surface 3.

Guide groves 8 and 9 receive downward extending members (not shown) ofthe telescopic sight. When those members are properly seated theyprevent forward or rearward motion of a properly fastened scope sight.

It is to be noted that the overall shape of mount 1 is such that it,advantageously, may be machined or made by an extrusion process. Thus,the cost of producing this mounting is appreciably less than others inthe prior art.

Attention is next directed to FIG. 3 which depicts an end view of mount1 and the barrel top sights as seen by a rifleman. When the rifle isproperly aligned on target,

(a) member 23 appear as shown above member 22,

(b) member 23 is situated substantially at the center of the outlineformed by the C-shaped interior of mount 1, and

(c) the apparent thickness a of the interior surface 2 shown by dot-dashlines is uniform.

Accordingly, any or all of the foregoing may be depended on for sightingthe rifle.

To further enhance the sighting capability of mount 1, rifling lines orgrooves running the length of interior surface 2 can be provided. Inaddition, surface 2 can be polished to enhance the light reflectivequalities of that surface. In practice, the mount was treated With ablueing compound in the customary manner. Due to the curvature ofsurface 2, however there was an appreciable increase in the ambientlight intensity along the sighting axis even though the surface lightreflective qualities are diminished by blueing.

FIG. 4 shows a side view of an alternative arrangement of mount 1 inwhich a portion of the bottom mount surface indicated by dimension x isremoved. In this manner the mount can accommodate top loading rifles.Oftentimes, the top receiver assembly surfaces of a top loading rifleare not in the same plane. To insure the proper positioning of scope 20on rifle 21, as indicated by dimension y a portion of the bottom mountsurface has an in creased thickness. This raises the front end of mount1 and aligns the scope.

It is to be understood that the herein before described arrangements areillustrative of the application of the principles of this invention. Forexample, the mount can be used on hand guns and on weapons capable offiring large diameter shells. In light of this teaching, it is apparentthat numerous other arrangements may be devised by those skilled in theart without departing from the spirit and scope of the invention.
